Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect. Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission. The generated ultrasonic waves are d… WebMar 9, 2024 · Multispectral optoacoustic tomography (MSOT) is a technique recently used in dermatology, which can provide 3D visualization. Using pulsed NIR to generate acoustic waves, under-skin details from a maximum of 1 cm depth are depicted, and the resolution reached is only 60 µm [5,28].
